Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

- * What is struct pid?
- *
- * A struct pid is the kernel's internal notion of a process identifier.
- * It refers to individual tasks, process groups, and sessions.  While
- * there are processes attached to it the struct pid lives in a hash
- * table, so it and then the processes that it refers to can be found
- * quickly from the numeric pid value.  The attached processes may be
- * quickly accessed by following pointers from struct pid.
- *
- * Storing pid_t values in the kernel and referring to them later has a
- * problem.  The process originally with that pid may have exited and the
- * pid allocator wrapped, and another process could have come along
- * and been assigned that pid.
- *
- * Referring to user space processes by holding a reference to struct
- * task_struct has a problem.  When the user space process exits
- * the now useless task_struct is still kept.  A task_struct plus a
- * stack consumes around 10K of low kernel memory.  More precisely
- * this is THREAD_SIZE + sizeof(struct task_struct).  By comparison
- * a struct pid is about 64 bytes.
- *
- * Holding a reference to struct pid solves both of these problems.
- * It is small so holding a reference does not consume a lot of
- * resources, and since a new struct pid is allocated when the numeric pid
- * value is reused (when pids wrap around) we don't mistakenly refer to new
- * processes.
